Abstract
Improvements in the procedures for the manufacture of hydrogen fluoride, in which by-product calcium sulfate is obtained, reacting calcium fluoride with sulfuric acid at a temperature within the range of around 121-316ºC, characterized by providing in the mixture Reactive of calcium fluoride and sulfuric acid more than three parts and up to about ten parts of calcium sulfate per part of calcium sulfate by-product produced.
